Process and device for cutting pieces of material to order, from a band of material, by using a cutting table equipped with a vacuum installation for holding the band of material in place and a workable, longitudinal and traverse slide on the cutting table, running along the desired cutting lines, which is controlled by a data processor for marking and data control,as the carrier of a cutting tool driven by ultrasound, for the purpose of which a conveyor belt with a base similar to a brush serves as the means of transport for the band of material in the cutting area and as a cutting base, which is moved, step by step, by means of a slide range that, for the finished cut of a piece of material, is larger than the cutting tool's most ample movement in the longitudinal direction , for which purpose, the cutting tool in each case is only moved following the transportation phase, with the conveyor belt being stationary all along the cutting lines. |
